-Your reporting tables keep needing derived columns - and until now, the answer was a SAS hook script.
+Every SAS team has a spreadsheet that "helps" load data into production.
 
-Change a price, and the revenue column updates itself. Stamp the user who made the change, in the same row, automatically. And when an email address doesn't look like an email address - block it before it ever reaches production.
+You know the one. Someone built it years ago, nobody fully understands it, and it writes straight to a table it probably shouldn't.
 
-Data Controller v7.13 ships live formulas in the editor grid. Configure a column with a rule like = PRICE * VOLUME and the value is computed on entry, spreadsheet-style, using the full function library (IF, SUM, ROUND and friends). A HARDFORMULA locks the column; a SOFTFORMULA lets the user override when the business needs it.
+What if that spreadsheet was wrong BEFORE anyone could hit send?
 
-It completes the story started in 7.12 with regex validation - HARDREGEX blocks invalid patterns outright, SOFTREGEX highlights them as a warning. Both are one row of config in MPE_VALIDATIONS. No code, no deployment.
+That's the idea behind Data Controller - a web app for SAS that lets business users change data safely. Every change is checked at the point of entry, goes for approval, and lands in a full audit trail. No new infrastructure - it runs on the SAS you already have.
 
-There are also special runtime values - so an audit column can read "sasdemo changed from orig-2" without anyone typing it:
+The latest release adds two things that used to require a developer:
 
-=IF( DC.ROW_STATUS ="U","unedited",
-  DC.USER_NAME &" changed from "& DC.ORIG_VALUE )
+→ Formulas. Type a rule like = PRICE * VOLUME and the revenue column computes itself - spreadsheet-style, in the browser, live.
 
-Full write-up with live screenshots (and how the rules flow from config table to grid):
+→ Pattern checks. "Must be a valid email." "Must be an integer." One row of config. Bad values are blocked or flagged before submission - not found in next month's report.
+
+Both are configuration, not code. If you can fill in a table, you can set them up.
+
+We wrote up how it works (with live screenshots of a bad email being caught red-handed):
